| 摘 要： | 目的]研究一定降雨条件下,伊犁河谷地区3个不同草地类型径流小区的减流减沙效果,以期为该区的水土保持工作提供借鉴。方法]采用野外人工模拟降雨的方法。结果](1)几种草地类型初始产流时间的长短依次为:角果藜伊犁蒿狗牙根裸地;(2)径流速率由大到小依次为:裸地伊犁蒿狗牙根角果藜;(3)泥沙含量由大到小依次为:裸地伊犁蒿狗牙根角果藜;(4)狗牙根减流因子的数值处于0.21~0.58之间,伊犁蒿的减流因子处于0.14~0.87之间,角果藜的减流因子则在0.02~0.11之间,狗牙根减沙因子的数值在0.16~0.76之间,角果藜的减沙因子处于0~0.42之间,伊犁蒿的减沙因子则在0.42~0.88之间。结论]水土保持效益最好的是角果藜,其次为狗牙根与伊犁蒿,裸地效果最差。

| Abstract: | Objective] The reduction effects of runoff and sediment in 3 different grasslands runoff plots were observed under certain rainfall condition in Yili river valley, to provide references for soil and water conservation in the area.Methods] Method of field artificial rainfall was used.Results] (1) The occurrences of initial runoff the several grasslands ranked as:Pod quinoa > Yili Artemisia > Bermuda grass > bare land; (2) The runoff of rate ranked as:bare land > Yili Artemisia > Bermuda grass > Pod quinoa; (3) The sediment concentration ranked as:bare land > Yili Artemisia > Bermuda grass > Pod quinoa; (4) The values of flow reduction factor of Pod quinoa, Bermuda grass and Yili Artemisia were 0.02~0.11, 0.21~0.58 and 0.14~0.87. The values of sediment reduction factor of Bermuda grass, Pod quinoa and Yili Artemisia were 0.16~0.76, 0~0.42 and 0.42~0.88.Conclusion] Pod quinoa got the best benefit for soil and water conservation, followed by Yili Artemisia and Bermuda grass, bare land performed the worst. |
